Anxiously awaiting a real reply about this mix.
My Impressions on the Blu-ray Tommy Mix
For those of you WHO have come here seeking guidance for a purchase decision of this mix, here are my 5.1 cents.
This release is in some ways parallel to the Pink Floyd DSOTM & WYWH releases, in the sense that we have multiple releases of multiple mixes on multiple formats. Some may find this annoying, as it may seem like an attempt to extort more money from the fan. I personally do not mind multiple variations as long as said variations are wide enough to add new depth and perspective on the underlying recordings. I believe this is the case here.
The Blu-ray mix of Tommy is dramatically different from the previously available 5.1 mix, and for the collector that is great news! Rather than say one is better than the other, I would suggest that they are unique perspectives. I do have a go-to version, but that is a matter of personal taste which is less important to the discussion here.
I give the release a 10 for a Who fan, and more like an 7 for a casual Who listener. I am a Who fan, so my posted vote is a 10. I sat down the other day and made direct comparisons of the DVD-A, the SACD, and the Blu-ray. By direct comparison I mean that I did not change the amp or channel settings when changing discs, so that the material as presented was evaluated. I have still not tried the channel reassignments suggested elsewhere.
Blu-ray Audio DTS
In direct comparisons this is quite a bit quieter at the same amp settings: this probably is a mastering function, and possibly means that more dynamics from the master tapes are represented here. I do not have a way to extract visual waveforms etc. from these discs. Perhaps someone else might comment on this.
The Blu-ray version sounds like a boutique mix for "fan consumption." The separation of elements is excellent, providing a great opportunity for analysis of production technique. This mix offers new perspective on familiar music, more dramatically so than the SACD or DVD-A mixes.
I like the Blu-ray version of 'Tommy Can You Hear Me' better: The guitars on this track are just sparkling in clarity, and at the end the vocal wanders around while on the SACD/DVD-A it is in a static position. You are more likely to encounter that sort of playful mixing on the Blu-ray version.
To me, the effect of having the drums largely (though not always) isolated to the left rear is interesting, but it makes the music seem smaller. (As an aside, I feel the same way about the piano on Van Morrison's Moondance). One of the things that makes The Who The Who is all the high testosterone bigness: both the egos behind the music and the raw huge power of the presentation. The Blu-ray sounds less huge in presentation because of the separation of elements. The SACD tends to widen the mix as compared to stereo while still feeling like a huge Who sound. The good news is that the Tommy recording has lots of more acoustic presentation where the hugeness is not missed.
I love that the Blu-ray menu access is more simple than the DVD-A
SACD DSD
In direct comparisons this is quite a bit louder at the same amp settings than the Blu-ray, but slightly quieter than the DVD-A. The sound is fuller in the low end, although a sub tweak might fill out the Blu-ray. This version feels more like a completed mix for "consumer consumption" with some discrete elements but more conservative mixing than the Blu-ray. The SACD has the benefit of LP outtakes, some of which are mixed in surround. For those who like DSD reproduction, the SACD is the only format that has this option.
DVD-Audio PCM 96K
In direct comparisons this is a little louder at the same amp settings than the SACD, and much louder than the Blu-ray. As with the SACD, this version has the benefit of LP outtakes, some of which are mixed in surround. The DVD audio is the only source of the three for the excellent video interview with Pete Townshend where he discusses mixing Tommy in surround. I am pretty sure this mix is identical to the SACD per other discussions. So if you don't need DSD, I would pick the DVD-A over the SACD.
In summary, I am glad to own all three versions. Each offers something different. My default for Tommy would be SACD DSD for general listening, and Blu-ray if I wanted to get fresh perspective on the music. Even at that, I think the Blu-ray is interesting enough to warrant repeated listenings.
I hope this helps!
See you around!
